MDVSA-2012:039

Problem description

A vulnerability has been found and corrected in libtasn1:

The asn1_get_length_der function in decoding.c in GNU Libtasn1 before
2.12, as used in GnuTLS before 3.0.16 and other products, does not
properly handle certain large length values, which allows remote
attackers to cause a denial of service (heap memory corruption and
application crash) or possibly have unspecified other impact via a
crafted ASN.1 structure (CVE-2012-1569).
